Morphometric analysis of baltira watershed using QGIS platform

Abstract

In India due to rising in the population, resources like land and water goes on decreasing. So, it is absolutely necessary to conserve these natural resources and exertion of the resources in an effective way. From the administrative point of view, the watersheds act as the basic units for conservation of resources. For detail characterization of landforms and properties, the morphometric analysis of basins is of great help in understanding by interpreting the information available from dimensionless analysis which helps to find out the linear and aerial aspects. Morphometric analysis is the most acceptable method to be considered for reservoir basin. For developing the topographic and geomorphologic conditions, it is necessary to understand various parameters of diverse basins. In this study, a detailed morphometric assessment is done by QGIS for Baltira watershed which covers an area of 273 km2. Baltira is one of the tributaries of Man River. The result of morphometric analysis reveals that watershed of Baltira in which geology is reasonably homogeneous, having high relief and steep ground slope. For this study, ASTER-DEM is utilized for watershed delineation and drainage parameter calculation by the hydrological module of QGIS software.
